This patent application is a continuation-in-part of U.S. patent application Ser. No. 10/291,238, filed Nov. 8, 2002, now abandoned, which claims the benefit of U.S. Provisional Patent Application Nos. 60/344,570, filed Nov. 9, 2001, and is also a continuation-in-part of U.S. patent application Ser. No. 10/777,016, filed Feb. 11, 2004, now U.S. Pat. No. 7,089,978, which claims the benefit of each of U.S. Provisional Patent Application Nos. 60/446,871, filed Feb. 12, 2003, 60/505,275, filed Sep. 23, 2003, and 60/530,701, filed Dec. 15, 2003 .
The present invention relates generally to tools and more particularly to tool attachment systems and methods for attaching and detaching tool attachments.
A router is a well known rotary cutting tool for routing a workpiece. Typically a router has a rotating bit which extends through a router base. At times it is desired to utilize a tool attachment such as a guide bushing, having a cylindrical extension, spaced around the bit, to guide the router along a template wall. The diameter of the cylindrical extension determines the distance between the bit and the template wall, which determines the resultant pattern.
Typically a guide bushing is attached to a router base by first attaching an adapter plate to the router base, and then attaching the desired guide bushing to the adapter plate, typically by fastening the bushing to the adapter plate. However, because adapter plates for particular router models and manufacturers typically have their own unique bolt patterns, retailers must stock many models of adapter plates and guide bushings.
The present invention is directed toward improvements over the prior art, which are particularly applicable to routers, and that may also have application to other forms of tool attachments.
The present invention has several aspects which are herein sought to be protected. In general, the present invention is directed toward a tool attachment and system and method for providing for quick attachment and detachment of such tool attachments, while also reliably securing and locating the tool attachment.
According to one aspect of the invention, a tool attachment is provided for mounting to a mounting adapter along a tool axis in which the mounting adapter includes an annular mounting surface and a plurality of mounting flanges angularly spaced about the axis. The tool attachment comprises an attachment housing having a generally circular attachment surface that is sized and configured to mate with the annular mounting surface of the mounting adapter. A plurality of attachment flanges project radially from the attachment housing along the attachment surface. These attachment flanges are arranged in a common plane generally perpendicular to the axis and are angularly spaced about the axis. The spacing between attachment flanges forms a plurality of gaps between adjacent pairs of the attachment flanges which provide sufficient clearance to receive the mounting flanges of the mounting adapter through these gaps.
Another aspect of this invention is directed toward a new method of releasably attaching a tool attachment to a mounting adapter about an axis. The method is directed toward a mounting adapter with an annular mounting surface and a tool attachment with an annular attachment surface. According to the method, the tool attachment is installed onto the mounting adapter along the axis to facilitate engagement between the first and second attachment service in a first direction along the axis. Relative rotation between the mounting adapter and the tool attachment is conducted to cause interlocking engagement between corresponding end flanges along the first and second attachment surfaces. This provides for retention of the tool attachment to the mounting adapter in a second opposite axial direction. Thereafter, the mounting adapter and the tool attachment are rotationally locked.
The present invention is thought to have particular application and advantages in router applications and therefore certain claims are directed toward such router attachment systems. According to this aspect, a mounting adapter is provided along an end face of a router housing in which the mounting adapter includes an annular mounting surface. A router attachment is provided that has an attachment housing with an annular attachment surface that mates with the annular mounting surface. The router attachment is rotatable between a release position and an attached position. The router attachment is removable from the mounting adapter in the release position and vertically engages the mounting adapter in opposing axial directions in the attached position. A lock is provided which locks the router attachment to the mounting adapter in the attached position to prevent relative rotation between the two components. The lock is subject to manual actuation to allow rotation between the router attachment and the mounting adapter to allow for detachment of the router attachment from the mounting adapter.
A further aspect of the invention is directed toward the router attachment system for a router comprises a mounting adapter plate that has a plurality of bolt holes and a central hole adapted for communicating the spindle of the rotor therethrough when the mounting adapter plate is mounted to the rotor housing. The bolt holes facilitate mounting of the mounting adapter to the router housing via a fastening operation. A router attachment is provided that is adapted to position the router. The router attachment attaches and detaches from the mounting adapter plate without bolts or fasteners. The rotor attachment is vertically and rotationally secured to the mounting adapter plate through engagement when attached to the mounting plate to prevent movement therebetween.
Other features and advantages of the invention will be apparent from the following specification taken in conjunction with the following drawings.
While this invention is susceptible of embodiment in many different forms, there is shown in the drawings and will herein be described in detail various embodiments of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the embodiment illustrated.
A universal router bushing adapter, generally designated 10, for permitting attachment of a router guide bushing 12 to any of a plurality of routers, such as router 14, is illustrated in the
The adapter 10 further includes a centering bit 26 having a first end 26 a dimensioned for insertion into a router chuck 28. The router chuck 28 is dimensioned to receive a bit of a first dimension, such as ¼ inch. The centering bit 26 further includes a first centering portion 26 b spaced from the first end 26 a. The first centering portion 26 b is in the form of a frustum. The first centering portion 26 b is generally solid.
For use with a router having a chuck dimensioned to receive a bit of a second dimension, such as ½ inch, the centering bit 26 also includes a second end 26 c dimensioned for insertion into the second dimensioned chuck. The centering bit also includes a second centering portion 26 d spaced from the second end 26 c. The second centering portion 26 e is in the form of a frustum.
The adapter plate 18 includes a central aperture surface 18 a defining a central aperture 38. The adapter plate 18 further includes three lips 40 disposed along the central aperture surface 18 a to engage three respective cooperative tapered lips 44 on the guide bushing 12. Each of the tapered lips 40 includes a protrusion 40 a (
To mount the guide bushing 12 to the router base plate 23, first the guide bushing 12 is secured to the adapter plate 18 (
The router guide bushing 12 includes four apertures 12 a, for improved visibility. Two of the apertures 12 a are smaller, to provide space for indicia 12 b, indicative of the diameter of the cylindrical extension 13.
With the present invention, retailers no longer must stock guide bushings for many different base plate configurations. Rather, all they need do is stock the universal adapter plate, and guide bushings for the universal adapter plate. Additionally, once the adapter plate 18 is in place on the router 14, other guide bushings 12, having different cylindrical extension diameters, can be readily interchanged.
Turning to a second embodiment of the present invention, an adjustable router guide attachment 110 for a router 111 is shown in the
The router mounting adapter 112 preferably comprises a quick attachment and release type of adapter as shown, which may comprise a locking and release mechanism that may be similar to that disclosed and taught in U.S. patent application Ser. No. 60/446,871, entitled “Universal Router Guide Bushing Adapter And Method” filed on Feb. 12, 2003, and as such the entire disclosure of this application is hereby incorporated by reference. The router mounting adapter 112 includes a collar 120 and a mounting plate 122, both of which may be formed of plastic material, or cast from metal material for heavier duty construction. The mounting plate 122 includes bolt holes that facilitate bolting of the mounting plate 122 to the end face of the router 111 generally concentric or coaxial about the router's spindle.
The mounting plate 122 includes retainers in the form of angularly spaced threads 124 on the outer periphery thereof, which are received by corresponding retainers in the form of angularly spaced threads 126 on the inner periphery of the collar 120. Engagement of the threads 124, 126 or other suitable form of retainers, provides for axial retention. In addition, a rotational lock 128 is provided between the collar 120 and the plate 122, which may comprise a movable catch or latch 130 which may be loaded via a spring 132 to releasably lock into a corresponding stop 134 such as a thread end face, snag or divot. In this embodiment, the spring loaded latch 130 is mounted to the collar 120, while the end stop 134 (and preferably multiple end stops 134 are provided to allow for different angular orientations although only one stop surface is needed for rotational locking) is formed in a corresponding location along the radial periphery mounting plate 122. By rotating the mounting plate 122 relative to the collar 120, the mounting plate 122 (and thereby the router 111) is removably and releasably secured to the collar 120 to provide for quick attachment and detachment of the router guide attachment 110.
It will be appreciated that the plate 122 may not be sold as part of the adjustable router guide attachment 110, since this plate 122 may be integrated into the end face of the router 111 rather than provided as a separate plate. Also, the plate may be provided from another application, e.g., such a bushing guide, and therefore another plate may not need to be provided, but only the collar 120 which interfaces and releasably locks with the plate 122. Also, the mounting adapter could take other forms such as bolting or otherwise securing the rail directly to router, but such alternatives are less preferred.
The collar 120 has a projecting mounting flange 136 to which the rail 114 is mounted 136. The rail 114 may be formed as an aluminum extruded member with dovetail or other locking type grooves 138 on opposed sides. Plastic end caps 140 may cover ends of the rail 114. To mount the mounting flange 136 of the collar 120 to rail 114, a dovetail slidable bar segment 142 is provided, which is an assembly of upper and lower component parts 142 a, 142 b is provided.
Each component part 142 a, 142 b of the bar segment 142 includes a dovetail profile 146 that is adapted to slide linearly within the dovetail groove 138 of the rail 114. The bar segment 142 includes a vertically extending shaft 144 (e.g. the threaded shaft of a bolt retained by the lower component) that is received through a corresponding hole 152 in the mounting flange 136. The top face of the slidable bar segment includes a pair of perpendicularly intersecting slots 148, 150 in the shape of a cross. The mounting flange 136 includes a complementary block portion 154 projecting vertically that is received into either of the slots 148, 150. To secure the collar 120, the mounting flange 136 is arranged on the bar segment 142, with the threaded shaft 144 projecting through the hole 152 and the block portion 154 received in one of the complementary slots 148, 150. A thumb screw 156 is threaded on the shaft 144 to attach the collar 120 and tightened to fix the position of the collar 120 relative to the rail 114. In particular, when the thumb screw 156 is not tightened down, the bar segment 142 and therefore the collar 120 may be linearly movable relative to the rail 114 through sliding contact between complimentary dovetail surfaces. However, when the thumb screw 156 is tightened, the upper segment component part 142 a is forced downwardly and the lower segment component part 142 b is forced upwardly wedging the components in the rail 114 and in effect clamping collar 120 in a fixed position relative to the rail 114.
Another aspect of the disclosed embodiment is directed toward the feature of a selectively movable edge guide assembly 118. This assembly 118 includes a linear edge guide 158 which may be formed from stamped sheet metal to provide a guide surface 161 extending in plane generally perpendicular to the linear axis of the rail 114. The linear edge guide 158 is secured to a bar segment 160, which itself comprise two component parts 160 a, 160 b, each of which includes of a complimentary dovetail profile 162 that is adapted to slide linearly within the dovetail groove 138 of the rail 114.
A handle 164 is provided that is extendible and retractable (see e.g.
When the handle 164 is retracted, the bar segment 160 is relaxed allowing edge guide assembly 118 to be linearly moved and repositioned to the rail 114 through sliding contact between complimentary dovetail surfaces. However, when the handle 164 is moved to an extended position, the cam surface 166 engages the bottom surface of the bar segment 160, causing the upper segment component part 160 a to be forced downwardly and the lower segment component part 160 b to be forced upwardly wedging the components in the rail 114 and in effect clamping the edge guide assembly 118 in a fixed position relative to the rail 114.
Another aspect of the disclosed embodiment is directed toward the feature of a centering pilot member 116 which comprises two component parts 116 a, 116 b, each of which includes of the includes a complimentary dovetail profile 180 that is adapted to slide linearly within the dovetail groove 138 of the rail 114. The centering pilot member 116 also includes a cylindrical bushing 182 with a central through hole 184 that is adapted to be nailed or screwed or otherwise fastened to a working surface. The bushing 182 is received in a cylindrical cavity 186 of the member 116 to provide for rotation/pivoting movement therebetween.
A screw 188 is threaded into a threaded hole in the upper component part 116 a and may be tightened to fix the position of the centering pilot member 116 relative to the rail 114. In particular, when the screw 188 is not tightened down, the centering pilot member 116 may be linearly movable relative to the rail 114 through sliding contact between complimentary dovetail surfaces. However, when the screw 188 is tightened, the upper segment component part 116 a is forced downwardly and the lower segment component part 116 b is forced upwardly wedging the components in the rail 114 and in effect clamping the centering pilot member 116 in a fixed position relative to the rail 114.
With the foregoing arrangement, the disclosed embodiment of the router guide attachment 110 is versatile and has different operational modes. As shown in
Turning to a third embodiment of the present invention, a router guide attachment 210 as shown in
As shown, a router guide attachment preferably comprises a quick attach and release type mounting adaptor as shown, which may comprise a locking and release mechanism that may be similar to that disclosed and taught in U.S. Provisional Patent Application No. 60/446,871, entitled “Universal Router Guide Pushing Adaptor And Method” filed on Feb. 12, 2003 or U.S. Provisional Patent Application No. 60/505,275, entitled “Adjustable Router Guide” filed on Sep. 23, 2003, and as such the entire disclosures of these applications are hereby incorporated by reference. To facilitate quick attachment and detachment, the housing 214 includes a collar portion 222 that is adapted to rotatably engage a relatively flat circular mounting plate 224 (see
Mounting plate 224 provides for vertical retention through the provision of a plurality of angularly spaced flanges in the form of threads 226 on the outer circular periphery thereof, which are received by and are adapted to engage corresponding flanges in the form of angularly spaced threads 228 on the inner circular periphery of the collar portion 222. Engagement of the threads 226, 228 thereby provides for axial or vertical retention, preventing relative vertical or axial movement of the router 212 (with mounting plate 224 attached), and the router guide attachment 210, once the corresponding threads 226, 228 are rotated into engagement with one another. Referring to
In addition to vertical retention, a rotational lock is provided in the form of the spring loaded lock actuator 218. As shown in
The lock tab 238 provides a stop surface that engages a corresponding stop structure 242 on the mounting plate 224 such as a flange end face as shown, or a snag or divot in the alternative. Preferably multiple end stops structures 242 are provided, one for each different set of threads 226, 228, such that the router 212 can be mounted at a corresponding different number of angular orientations.
To facilitate attachment of the router 212 with the mounting plate 224 mounted thereto, to the guide attachment 210, the mounting plate 224 is set into the collar portion 222 and then relative rotation between the two components is facilitated to cause the threads 226, 228 to rotate pass one another. The lock tab 238 may include a cam surface 239 which engaged, by the outer surface of the mounting plate 224 initially back drives the lock actuator 218 to avoid interference with the rotational movement. Once relative rotation occurs, the lock actuator 218 automatically advances under the spring bias to move the lock tab 238 into locking engagement with the corresponding stop structure 242 once rotating there past to prevent back rotation. In addition, end of movement stops 244, 246 are respectively provided on the collar portion 222 and the mounting plate 224 that come into contact with one another to prevent over rotation of the mounting plate 224 relative to the collar portion 222. At this point, the router 212 and mounting plate 224 are rotationally locked to the housing by virtue of the lock actuator 218 being spring-biased forward and preventing the mounting plate from rotating out of position. At the same time, the corresponding threads 226, 228 axially or vertically retain the housing 214 to the router 212 and mounting plate 224.
A secondary form of lock mechanism is provided in the form of raised ribs which provide snaps 245, 247 on the corresponding threads 226, 228 of the collar portion 222 and mounting plate 224. As these snaps 245, 247 rotate past one another during the rotational movement described above, they snap past each other. This provides a secondary additional means (in addition to lock actuator 218) for rotationally locking the collar portion 222 and the mounting plate 224. Accordingly, it will be readily appreciated that redundant rotational locking means is thereby provided, however, an alternate embodiment of the invention may include only one locking means. The rotational locking facilitated by snaps 245, 247 is facilitated by virtue of the resilient nature of the material selected for the collar portion 222 and/or the mounting plate 224. As such, the rotational locking force provided by the snaps can be overcome radially (by virtue of corresponding cam surfaces on trailing faces of the snaps), which allow the mounting plate 224 to be readily detached from the collar portion 222 with manual force.
When it is desired to release the router guide attachment 210 from the router 212, it can be accomplished relatively easily simply by pulling the finger pull tab 232 thus retracting the lock actuator 218. When this happens, the mounting plate 224 and collar portion 222 are no longer rotationally locked with one another, and the router can be rotated to release the router and mounting plate 224 from the collar portion 220 of the router guide attachment 210.
The third embodiment includes an arm portion 248 extending radially from the collar portion 222. In the outboard of the finger pull tab 232 is a handle in the form of a rotatable knob 216. The knob 216 includes an axially extending threaded shaft portion 252 that is inserted into a hole 254 formed in the housing 214 and is secured thereto by a threaded fastener nut 256 on the underside of the housing 214. The knob 216 can be manipulated by hand to facilitate easier manipulation and positioning of the router when the router guide attachment 210 is mounted thereof.
The preferred embodiment of the milling system according to the present invention (
The templates, in particular the movable template 503, are designed so that they are mutually compatible and will complement each other for the cutting of new patterns. However, this only applies to templates with the same-size template. In one particular refinement of the milling systems according to the present invention, through the use of a guide bar 513 adjustable in the X- and Y-directions, an expansion of the pattern is possible. On the base plate 502 of the milling system according to the present invention, there is a means 510 provided for securing of this guide bar. The guide bar 513 can be locked in place, for example, by use of a locking bolt 515. When this locking feature is used, the locking bolts 515 are inserted into the holes drilled for the locking unit 514. The distance between the drilled holes for the locking unit 514 is a defined value, in order to ensure the precise movement of the milling system in the X- or Y-directions.
Selection of the pattern to be milled is made by using a pattern selection sheet included for each milling system. Thus, the user can obtain information concerning which pattern cutouts (examples) 504 are needed for forming the desired pattern.
In the simplest case, the actual milling process proceeds as follows: in the preferred embodiment of the milling system according to the present invention, the base plate 502 is placed upon the workpiece, suitably aligned, and then locked in place by using threaded clamps, for example. The rotatable template 503 must remain movable mobile in this case. The size of the tracing collar 516 and also the router bit 517 to be used are suggested on the router 511 for each pattern. Then, the cutting depth of the router 511 is set. Next, the router 511 equipped with tracing collar 516 and router bit 517 is guided along the inside edges of the pattern cutouts (example) 504 belonging to the pattern in the template 503.
According to the specified cutting pattern, the movable template 503 is moved into a new position after each milling process by shifting, turning, sliding or rotating. These steps are then repeated until the desired pattern has been completely formed. For cutting particular patterns, often only partial segments of the pattern cutouts (example) 504 are needed. Based on the pattern selection sheet, the user will be able to obtain information indicating which partial segments of the pattern ring of the router are to be followed.
A milling system 520 for milling patterns into the workpiece 507 is illustrated in
The baseplate 522 includes twenty-four recesses 534, which are sequentially labeled A, B, C, D. The template 526 includes six protrusions 536, which locate the template 526 relative to the baseplate 522.
The baseplate 522 includes opposing notches 538, and the template 526 has a center positioning aperture 524 b for aligning the workpiece 507 with the milling system 520. Additionally, the baseplate aperture 524 has a beveled aperture surface 524 a, and the template 526 has a cooperatively beveled outer surface 527.
The template has a plurality of pattern cut-outs 527. The template 526 further has an upper surface 526 a and a lower surface 526 b. The upper surface 526 a is flush. The lower surface 526 b has cored out segments 526 c to reduce material cost. The baseplate lower surface 526 b is textured.
In order to view a resulting pattern before milling the workpiece 507, a pencil guide 540, illustrated in
A preferred embodiment of a system 544 for vertically supporting a rotary cutting tool 546 is illustrated in
The tool support system 544 comprises a transparent base 548 and a three posts 550 extending upwardly from the base 548. The base has a lower surface 548 a having two, generally circular ribs 548 a (
The system 544 further includes a tool support 552 for supporting the rotary tool 546. The tool support 552 has a plurality of sleeves 554, one associated with each of the posts 550. Each of the sleeves 554 includes first and second bushings 555 a, 555 b. The sleeves 554 slidably receive respective ones of the posts 550. The system still further includes two springs 556 disposed in respective spring sleeves 557 for biasing the tool support 552 away from the base 548. The springs 556 each have a first end 556 a disposed in the spring sleeve 557 and a second end 556 b engaging the base 548.
The system 544 also includes a gauge 560 having one end 560 a secured to the tool support 552 by a set screw 561 and the other end 560 b adapted to engage the base 548 for selectively limiting the travel of the tool support 552 towards the base 548, which sets the depth of cut into the workpiece 507. The gauge is graduated, to display the selected depth of cut.
The tool support 552 includes a threaded opening 564 to receive a threaded nose 566 of the rotary tool 546. The tool support 552 also includes a pair of handles 568 for permitting a user to move the tool support 552 relative to the base 548.
The system 544 also includes a spring loaded release 576 for locking the tool support 552 in a position a selected distance relative to the base 548.
The base 548 further includes a vacuum attachment 578 to attach a vacuum device (not shown) to remove cuttings through the large openings 570 a in the guide bushing 570.
